Abstract (en)
[origin: WO9922307A1] A data interface for transferring data between processors which is formed of write registers (12) in which the data from a data sending write processor are written in accordance with a clock signal, read registers (13) in which the data written in these write registers are transferred by a later clock action and written, and from which the data are read out by a data receiving read processor, a write control means (15, 14-1 to 14-n) for writing data selectively in a register among the write registers in accordance with an address signal and a write signal from the write processor, and a read control means (16, 17) for reading data selectively from a register among the read registers in accordance with an address signal from the read processor. Owing to a double buffer structure in the write registers and read registers, address and data signals are connected separately on the write side and read side, so that the transfer of data can be carried out with the processors not interfering with each other.
